Research on Copolymering Mechanism of High Performance PAN-based Precursor and Spinning Process

This paper discusses the copolymering mechanism based on practical experience,and,using results from an SEM analysis, also discusses the spinning process. The experiment shows that copolymering included four stages,and the copolymering temperature was below the decomposing temperature. A drawing stretch ratio of about seven was selected in order to make high performance precursor and optimum property carbon fiber.
